LOADEB.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed October 29, 1907. Serial No. 899,751.

To all whom it may concern:

Be it known that 1, JOHN E. J ARBOE, citizen of the United States, residin at Red Cloud, in the county of Webster and State of Nebraska, have invented certain new and useful Improvements in Loaders, of which the following is a specification.

This invention has for its object an improved construction of loader of that type which embody a scoop designed to scrape fertilizer, or the like, as the machine travels forwardly and raise the loaded scoop to an elevated position at which the load can be dumped, and the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and then oint out the novel features in the appender claims.

For a full understanding of the invention, reference is to be had to the following de scription and accompanying drawings, in which:

Figure 1 is a perspective view of my apparatus; Fig. 2 is a sit e elevation thereof; Fig. 3 is a top plan view; Fig. 4 is a detail side elevation of a modified form of scraper that may be employed; and, Figs. 5, 6 and 7 are detail perspective views 0' other modifications relative to the scraper formation.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

My improved loader embodies a framework which in the present instance comprises forwardly divcrging longitudinal beams 1, a front cross beam 2, and a rear cross beam 3. 4 designates the drivers seat at the rear of the framework.

5 designates a caster-wheel at the rear of the framework and 6 an axle which is mounted at the front of the framework and on which the front traveling wheels 7 are journaled. These wheels 7 are formed with ratchet hubs, so that the axle 6 will be turned when the machine travels forwardly, but will have no motion imparted to it when the machine travels rearwardly as the steam is backed.

8 designates the oted at its middle rear of the rear cross doubletree which is pivbeam 3, and 9 desigto the framework in thenates the hold-backs secured to the front ends of the longitudinal beams 1.

Preferably U -shaped brackets 10 are mounted upon the rear cross beam 3, and arms 11 are pivotally mounted at their rear ends in the respective brackets 10, to swing about horizontal axes. The arms 11 are connected together at their front ends by a cross bar 12. Hangers 13 project forwardly and downwardly from the .front ends of the arms 11 and are formed with slots 14 designed to accommodate the outwardly projecting pins 15 secured to two sides of the scoop'16. The plate 17 is desi ned to straddle each of the pins 15, said p ate being secured by a thumb nut or the like in an adjustable manner to the hangers 13 so as to increase or decrease the size of the slot 14 and thereby regulate the amount of vertical play of the scoop with respect to the han ers. A bail 18 is secured to the cross-bar 12 o the arms 1 1, said bail being provlded with a ring 19 and the cable 20 is connected at one end to said ring and extends over a pulle or sheave 21 journaled in the up or ends 0 standards 22 mounted upon the ront cross beam 2 of the framework.

The other end of the cable 20, is connected to a drum 23 to wind thereon, said drum being mounted loose on the front axle 6. The drum 23 is formed with a clutch member designed for engagement with a movable clutch member 24 splined or otherwise slidingly mounted on the axle, and held to turn therewith.

25 designates a shipper bell crank lever which is fulcrumed at its elbow on the front cross beam 2 and which is rovided with the usual yoke encircling a co lar on the clutch 24 so as to effect the engagement of the clutch with the drum or the disengagement of the two to either couple the drum to the axle or allow the drum to run free. A link rod 26 connects one arm of the shipper lever 25 to a hand lever 27 fulcrumed 0n the rear cross beam 3. A detent 28 is adapted to engage a ratchet 23 formed on one head of the drum 23 and said detent is connected by means of a cord or rope 29 to another hand lever 30 fulcrumed on the rear cross-beam 3.

The scoop 16 is provided at one side with an upwardly extending post 31 having a rearwardly extendin end to which a latch rod 32 is connected. e latch rod 32 is rovided at its rear end with a handle 33 an extends through a guide loop 34 secured to and projecting upwardly from one of the swinging arms 11. This guide loop is rovided with a transverse pin 3 1i designed or engagement in either one of two keepers or notches 35 formed in the lower edge of the latch rod 32. A s ring 36 encircles the latch rod at the rear of t e guide loop 34. and bears against such loop and against a cross pin or collar in the latch rod, with a tension to move the latch rod rearwardly.

The scoop 16 may be rovided with a solid bottom 37 formed with side flanges 37 secured b bolts to the sides of the scoop frame an designed to rest u on and be secured to a bottom flange of t e frame. The bolts preferably extend through vertical slots in the scoop frame, so as to provide for a limited vertical play of the bottom of the scoop. If desired, this solid bottom, which is detachable, may be removed and tines 38 substituted therein, the said tines being secured by bolts or the like in the scoop frame, as shown.

In the practical o eration of in improved loading machine, t e team hitc ed to the machine is driven forwardly with the scoop resting upon the ground, either to grade a road, or e evate fertilizer, or any other material, with the scoop resting upon the ground and the clutch drawn out of engagement with the drum. Durin this portion of the operation, the latch ro is held in engagement with the pin 34 so as to hold the scoop rigid, as against any tilting or dum ing movement, on the pins 15 as an axle. hen the scoo has been filled, the driver will push forwar y upon the hand lever 27 to effect the engagement of the clutch with the drum, which, up to this point has been uncoupled from the axle. This coupling of the drum to the axle will ma estly effect the winding up of the cable upon the drum and cause the arms 11 to be raised, the pawl or detent 28 running free over the ratchet 23" on the drum. When the scoop has thus been elevated to the desired point, the operator will pull rearwardly upon the hand lever 27 and uncouple the drum from the axle, while the detent of course will hold the arms at the required elevation. The scoop may now be dumped of its load by the operator disengaging the latch rod from its pm 34: and the welght of the load will cause the scoop to tilt to discharge its contents at any desired point or into any desired receptacle. The scoop may then be lowered upon its supporting arms and the operation repeated as often as desired. The weight of the filled scoop is, of course, greater than the tension tion. hand on the rear end 0 the latch rod during operation, to insure the scraping or scoopin that the latch rod will not become disengaged from the pin 34*.

If desired, a box 39 may be secured to the rear end of the framework, to add weight to the machine.

Having thus described the invention, What is claimed as new is:

1. In a machine of the character described, the combination of a framework, vertically movable arms pivotally mounted on the framework, a scoop pivotally mounted between the free ends of said arms, means for raising and lowering the arms on the framework, the scoop being provided with an upwardly extending post, a guide loop secured to and pro'ecting upwardly from one of the arms, a latch rod mounted to slide through said loop and connected at its front end to the post, said latch rod being provided with a keeper and the loop being provided with a cross pin designed for engagement with said keeper, and an expansion spring secured to the rear end of said latch rod and bearing against said loop and designed to move the latch rod rearwardly in the loop, as and for the purpose set forth.
